Hot Forging Simulation Analysis and Application of Microalloyed Steel Crankshaft
In this paper, the hot forging process of microalloyed steel for crankshaft was investigated. The crankshaft model was built according to the data, directly measured from the blocker crankshaft blank. The simulation of crankshaft forging was carried out by FEM software ansys/ls-dyna. The changes of structure and temperature field were simulated in the course of hot forging. The relationships between the metal flow rules and temperaturefield in the crankshaft were described. And the shapes of centerline defects were analyzed during the crankshaft forging. In order to improve the material utilization ratio, a near-net-shape design is put forward according to the reversed analysis.
